FOOT FOR SAN D-LEVERS.

SPECIFICATION forming part of Letters Patent No. 401,611, dated April16, 1889.

Application filed May 7, 1888. Serial No. 273,071- (No model.)

To all 101 2 0772 in may concern:

Be it known that I, CHARLES VEZIE, a citizen of the United States, and aresident of Deuison, in the county of Grayson and State of Texas, haveinvented certain new and useful Improvements in Feet or Castings forSand-Levers; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 is a perspective view of myimproved casting or foot for sand-levers, show ing the same secured inoperative position to the lower end of a sand-lever and in proximity toseveral of the parts of the mechanism employed in well-boring. Fig. 2 isa perspective view of the casting removed from the lever, and Fig. 3 isa view of several modifications of the shoe or casting removed from thesand-lever.

Similar letters of reference denote corresponding parts in the severalfigures.

My invention has relation to that class of devices known as castings orfeet for the lower ends of sand-levers, and which are adapted to rock insuitable bearings secured to the main sill of a derrick employed in theboring of oil or other wells, whereby mechanism, substantially ashereinafter described, is thrown in and out of gear when desired.

To this end my invention consists in the improved construction andcombination of such a device, as will be more clearly set forth in thefollowing description.

In the accompanying drawings, the letter A denotes the main sill of aderrick employed in well-boring, and which is formed with a bearing, 13,having an aperture, 5, formed in its center.

C denotes the sand-lever, of the usual construction, to the lower end ofwhich is secured my improved foot or casting D, consisting of the solidcylindrical body E and the upwardly-proj ecting wings F, formed at rightangles to each other, thereby producing a two-sided socket. Theintermediate portion of this cylindrical body E, which forms a base forthe two-sided socket, is preferably cast square, as shown at G, whichsquare part forms a solid bearing for the lower end of the sand-lever.This casting is secured to the lower end of the lever by means of boltsH, inserted through the holes I in the wings. The foot or casting is nowjournaled in the bearing B of the main sill of the derrick, so as torock back and forth.

J indicates the drive-wheel journaled in suitable bearings, and fromwhich motion is imparted to the drill-reel K by means of the belt L.This drill-reel acts directly upon the drill mechanism, a furtherdescription of which is deemed not necessary. Journaled with one end ofits shaft Min a rocking bearing, N, and with the other end of its shaftin a bearing, 0, in the side of the sand-lever, is a sand-reel, P,which,by the rocking of the said sand-lever, may be brought into andthrown out of gear with the drive-wheel by means of the frictionalgearing Q, one wheel of which is upon the shaft of the drive-wheel,while the other wheel is upon the shaft of the sand-reel.

A chain or rope, R, is secured to the sandreel and passes 'over a pulleynear the mouth of the well, and to that end is secured to the sand-pump.After the boring has gone on for a considerable length of time the drillis removed and the sand-pump is dropped into the well and becomes filledwith the borings. Now the sand-lever is rocked forward by the workmanpulling upon the rope R, which throws the friction-wheels into contactor gear and causes the sand-reel to be revolved, which, in winding therope or chain around it, raises the sand-pump.

I would have it understood that I do not claim the mechanism herein setforth as part of my invention, and have only shown those parts as wasthought necessary to illustrate the object of my invention, the well,derrick, and sand-pump not being shown, as it is thought the device willbe readily understood when taken in connection with those parts nowillustrated.

If desired, the cylindrical body may be cast with only one wing, or, onthe other hand, with three or four, as shown in Fig. 3. In

either case the operation of the invention will be the same, as thecylindrical body portion is really the essential part of the invention.

It will be seen that my invention is employed instead of a knuckle post,which is objectionable for many reasons, and particularly for the reasonthat the parts are apt to become Worn and to work loosely or to becomeclogged in its joints with dust, 850., which will accumulate and adhereto the joints, which are usually lubricated, thus preventing a free andeasy movement of the sandlever.

This invention is not necessarily limited to Well-boring mechanism, asit can be employed in any class of machinery wherein a rocking lever isemployed with the same result as herein set forth.

From the foregoing description, taken in connection with theaccompanying drawings,

the operation and advantages of my invention will be readily understoodwithout requiring an extended explanation. It Will be seen that it issimple in construction, formed of but a few parts, and that it isexceedingly useful for the purpose for which it is designed.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- In a foot or casting forsand-levers, the combination of the semi-cylindrical bearing having anaperture formed in its center, a cylindrical body working in the saidbearing and having a square intermediate portion adapted to fit in thesaid aperture, upward-extending- Wings made integral with the body andforming a socket, and a lever fitting in the said socket, substantiallyas described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

CHARLES VEZIE.
